Simplifying x2 + -18x + 23.24 = 0 Reorder the terms: 23.24 + -18x + x2 = 0 Solving 23.24 + -18x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-23.24' to each side of the equation. 23.24 + -18x + -23.24 + x2 = 0 + -23.24 Reorder the terms: 23.24 + -23.24 + -18x + x2 = 0 + -23.24 Combine like terms: 23.24 + -23.24 = 0.00 0.00 + -18x + x2 = 0 + -23.24 -18x + x2 = 0 + -23.24 Combine like terms: 0 + -23.24 = -23.24 -18x + x2 = -23.24 The x term is -18x. Take half its coefficient (-9). Square it (81) and add it to both sides. Add '81' to each side of the equation. -18x + 81 + x2 = -23.24 + 81 Reorder the terms: 81 + -18x + x2 = -23.24 + 81 Combine like terms: -23.24 + 81 = 57.76 81 + -18x + x2 = 57.76 Factor a perfect square on the left side: (x + -9)(x + -9) = 57.76 Calculate the square root of the right side: 7.6 Break this problem into two subproblems by setting (x + -9) equal to 7.6 and -7.6.Subproblem 1
x + -9 = 7.6 Simplifying x + -9 = 7.6 Reorder the terms: -9 + x = 7.6 Solving -9 + x = 7.6 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + x = 7.6 + 9 Combine like terms: -9 + 9 = 0 0 + x = 7.6 + 9 x = 7.6 + 9 Combine like terms: 7.6 + 9 = 16.6 x = 16.6 Simplifying x = 16.6Subproblem 2
x + -9 = -7.6 Simplifying x + -9 = -7.6 Reorder the terms: -9 + x = -7.6 Solving -9 + x = -7.6 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + x = -7.6 + 9 Combine like terms: -9 + 9 = 0 0 + x = -7.6 + 9 x = -7.6 + 9 Combine like terms: -7.6 + 9 = 1.4 x = 1.4 Simplifying x = 1.4Solution
The solution to the problem is based on the solutions from the subproblems. x = {16.6, 1.4}
